3Very high frequency — (VHF) is the radio frequency range from 30 MHz to 300 MHz. Frequencies immediately below VHF are denoted High frequency (HF), and the next higher frequencies are known as Ultra high frequency (UHF). The frequency allocation is done by ITU. Common …
4very high frequency — The range of radio frequencies between 30 and 300 MHz. Portions of this band, 108 to 118 MHz, are used for certain NAVAIDs (navigational aids); 118 to 136 MHz are used for civil air to ground voice communications. Other frequencies in this band… …
5High frequency — (HF) radio frequencies are between 3 and 30 MHz. Also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres). Frequencies immediately below HF are denoted Medium frequency… …
6Very low frequency — or VLF refers to radio frequencies (RF) in the range of 3 kHz to 30 kHz. Since there is not much bandwidth in this band of the radio spectrum, only the very simplest signals are used, such as for radio navigation. Also known as the myriameter… …
